- 2. Description of Related Art
- An electrical connector includes an insulative housing and a plurality of contacts upwardly secured into passageways of the insulative housing. Each contact defines a retention portion interfered with the passageway, a contacting portion protruding from a mating face of the insulative housing and an elastic portion receiving in the receiving passageway and connecting with the contacting portion and the retention portion. In a process of the electrical connector mating with a complementary connector, a lateral pressing force is exerted on the contacting portions to result the contacting portions moving to the mating face. The pressing force is also exerted on the elastic portions to result in deformation of the elastic portions. Thus, an electrical connector with contacts prevented from deformation is desired to overcome the disadvantages of the related art.
- Hence, the present invention is directed to solving this problem in the related art.
- An object of the invention is to provide an electrical connector with improved contacts prevented from deformation and improving intensity.
- In order to achieve the object set forth, an electrical connector includes an insulative housing defining a mating surface, a mounting surface and a plurality of passageways running through the mating surface and the mounting surface and a plurality of contacts upwardly assembled into the corresponding passageways. Each of the contacts defines an upright retention portion interfered with the passageway, a pair of elastic arms extending from the retention portion and spaced apart with each other and a lying V-shaped contacting portion formed by a distal end of each elastic arms bending and extending beyond the mating surface of the housing. Each contact defines a connecting portion connecting with the pair of elastic arms and received in the passageway.
- Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
